This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Current environmental and economic trends have forced grid operators to maximize the utilization of the existing assets, which is causing systems to be operated closer to their stability limits than ever before. This requires, among other things, better knowledge and modelling of the existing power system equipment to increase the accuracy of the assessment of current stability margins. This research investigates the possibility of improving the quality of load modeling. The thesis presents a review of the traditional methods for estimation of load model parameters and proposes to use Improved Particle Swarm Optimization. Different algorithms are tested and compared in terms of accuracy, reliability and CPU requirements using computer simulations and real-data captured in a power system. Estimation of frequency and power components has also been studied in this thesis. A review of the existing methods has been provided and the use of an Unscented Kalman Filter proposed. This nonlinear recursive algorithm has been thoroughly tested and compared against selected traditional techniques in a number of experiments involving computer-generated signals as well as measurements obtained in laboratory conditions.

Download or read book Power System Stability written by László Rácz and published by Elsevier Publishing Company. This book was released on 1988 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this book is to investigate the stability problems of power systems by using state-space analysis. The authors have aimed to meet the need for a book that would cover fairly briefly the theoretical and well as practical aspects of the problem, including up-to-date methods of calculation and stability improvement. When preparing the text, they have assumed that the reader has a basic knowledge (but not above graduate level) of network theory, matrix algebra and control theory. The book combines the simplicity and transparency of the classic stability principles with the advantages of modern treatment based on system theory and state-space techniques. Theoretical passages are always accompanied by analog or digital computer study results. Detailed analysis is given of voltage regulator and field governor effects as far as they influence the steady-state and/or transient stability of generating units. This is the first book in the field to treat in detail the stability questions of long distance, EHV power interconnections. In view of increasing precision requirements, the usefulness of different simplified stability models is widely dealt with.

Download or read book Modelling Control and Stability Analysis of Photovoltaic Systems in Power System Dynamic Studies written by Gustav Lammert and published by kassel university press GmbH. This book was released on 2019 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates the impact of: i) the low voltage ride-through and dynamic voltage support capability; ii) the active current recovery rate; iii) the local voltage control; and iv) the plant-level voltage control of large-scale photovoltaic systems on short-term voltage stability and fault-induced delayed voltage recovery as well as transient and frequency stability. The power system dynamic performance is analysed using state-of-the-art methods, such as phasor mode time-domain simulations and the calculation of the critical clearing time that determines the stability margin. Moreover, the recently developed Kullback-Leibler divergence measure is applied to assess the quality of the voltage recovery. Drawbacks of this metric are outlined and a novel metric, the so-called voltage recovery index, is defined that quantifies the delayed voltage recovery more systematically. The studies are performed with a generic photovoltaic system model and typical model parameters are used that were determined in collaboration with a manufacturer. The stability analysis is performed in DIgSILENT PowerFactory using: i) a one-load infinite-bus system; and ii) an IEEE multi-machine voltage stability test system, namely the Nordic test system. The results show that with the adequate control of photovoltaic systems, power system dynamic performance can be significantly improved.
